To all whom it may concern. 4 Be it known that I, EDWIN E. BARNEY,

citizen of the United States, and resident of mon support or fulcrum wire.

In carrying out my invention I provide type bars each having integral pivot portions between which and the body portion of the type bar a relative movement may be effected without removing the type bar from its support, this relative movement being facilitated by the employment of a locking tool which cooperates both with the type bars individually and also with their support, and enables the length of the bar to .be permanently Variedso as to alter the relationship between the type or types thereon and the printing point on the platen.

To the above and other ends my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out 'in the claims.

One form of myv inyentio'n is illustrated in the accompanying drawings wherein- Figure 1 is a side elevation partly in section illustrating a type bar embodying my invention, the support for said type bar and its actuating devices. ig. 2 is a corresponding view of said type bar in a different position showing the locking device or tool appliedther'eto. Fig. 3 is a fragmentary front elevation partly in section of a type bar segment or support with several type bars mounted thereon, the section being taken on a vertical plane indicated by the dotted line a in Fig. 1. Figs. 4 and 5 are side elevations partly in section illustrating type bars after adjustment, the alteration in the bars being exaggerated for clcarnessof illustration. Fig.- 6 is a de tached perspective View of a part or element hereinafter referred to as a locking tool or adjusting device.

The nature of my invention is such that 1t may be adapted to various styles of typewrltlng machines. In, the accompanying drawings I have illustrated a conventional type bar support or segment l for frontstrike typewriting machines, said segment being secured by screws 2 to the top plate 3 of the machine frame. The platen 4 is diagrammatically illustrated as shiftable, and the segment as fixed, but this relationship may be reversed, that is, the segment may be shiftable and the platen non-shift able; or neither of the elements need'be shift-able so far as the purposes of my invention are concerned. The segmental type bar support is formed with a series of slots 5'which are radial with respect to the printing point indicated at a: in Fig. 3 and in other views. At its front the segment is formed with an arcuatei slo-t-way 6 whose center is the printing point. Seated at the rear of this slot-way is a segmental pivotal support or wire 7 which is common to all of the type bars. This wire may be secured 'to the type bar segment-in any suitable way. As illustrated the ends of the wire are threaded and receive locking nuts 8 which when screwed in, seat themselves in depressions in the ends of the bearing portions of the segment 1, thereby detaehably securing the wire 7 in place. Pivoted on the fulcrum wire 7 and seated in the slots 5 are type bars each designated as a whole by the numeral 9 and which will be .herein after more particularly described. Any suitable key-controlled actuating devices for moving the type bars from their normal positions of rest, at which time their free end portions are supported by a type bar rest 10, may be employed. As illustrated in the drawings, each set of type bar actuating devices comprisesa link 11 which is pivotally connected at 12 with a type bar. The link extends rearward and is connected at 13 with the upwardly vex tending arm of a bell crank 14, fixedly pivoted at 15 and having a rearwardly extending arm which is connected by a link 16 with a keylever 17 fulcrumed at the rear at 18 and terminating at its forwardend portion in a key 19,

each key lever being provided with a restoring spring 20.

The type bars extend forward from the pivot wire 7 and their free end portions are provided with lower and upper-case types 21 and 22. By depressing a key 19 the associate actuating" devices are operated, causing the type bar to swing to the print I ing point and the lower case type 21 to cooperate with the platen. By shifting the platen to the dotted line position in Fig. 1, which may be accomplished in any suitable way, the upper-case type 22 is rendered operative.

In the present instance the type bars are or may be made of sheet metal. The rear or pivot end portion of the bar is enlarged and generally circular as indicated at 23. This portion is cut or formed with a C-shaped slot 24; which is initially or normally concentric with the axis around which the type bar' swings. The pivotal portion of the bar is thus divided into two concentric eyes 25 and 26 separated from each other by'the width of the slot 24; and connected by a narrow connecting portion or neck 27. The neck is preferably compressed to reduce its thickness, so that when subsequently adjusting the bar any bulging of the neck which may result from bending it, will not cause the bar to bind in its bearing slot 5. The portion 26 forms a bearing eye, this portion having a bearing hole in it through which the pivot wire 7 passes. This hearing eye 26 is preferably integral with the body portion of the bar by which it is surrounded and with which it is connected by the neck portion 27. The construction" is such that the bar may be readily varied in length by altering the relationship between the bearing eye portion 26 and the body of the bar, this being effected by relatively moving the two parts so as permanently to alter their relationship.

To facilitate the relative movementv between the body of thev bar and its bearing eye, I preferably employ an adjusting device or looking tool which is shown detached in Fig. 6 and in use in Fig. 2. 'Said device is designated as a whole by the numeral 28. It is bar-like in form and should be rectangular in cross section at least at'its enga type bars being formed at the sides of the pivots opposite from the necks 27 with notches or slots .30 wide enough to receive the adjusting or locking tool.

The use of the tool in connection with my novel type bar may be briefly explained. It

will be understood that in assembling the set or series of type bars in the machinethey are entered in their respective radial slots 5 and the pivot wire 7 is then introduced in place, passing from one end of the segment to the other and through the bearing holes in the type bars which are thereby threaded on the pivot wire. Then said wire is secured in place by the locking nuts 8. The distance between the pivotal axis of the type bars and the types on said bars may slightly vary in ditferent'cases so that onebar may be a trifle too lopg and another a trifle too short; and it is necessary to render the bars uniform in respect of length so that the types may properly aline for printing purposes. In the present case in adjusting a type bar it is swung toward the platen until the types are in proximity thereto as shown in Fig. 2. This brings the notoch 30'in the type bar in register with the slot 6 in the type bar segment and permits the lockin tool 28 to be introduced into the slots 6 an 30, the notch 29 in the tool engaging or embracing the portion 25 of the type bar back of the notch 30therein.. As will be understood from Fig. 2 the tool thus locks the portion 25 of the bar in the vicinity of the notch 30 in rigid relationship with the seg ment 1. Suppose as indicated at Fig. 2 the bar is a trifle short sothat its lower case type would strike below the printing point an, as at. m. It is in such case desirable to lengthen the bar or increase the distance between its pivotal axis andthe types by a distance corresponding to the distance between the point :0 and the printing point 00, which distance is purposely exaggerated in Fig. 2 for clearness of illustration. In such case the adjuster grasps the bar near its type end and forces it slightly away from the platen. The bearing eye 26' isat all times held from movement transverse of the pivot wire by the pivot wire itself, and since 'the front of the part 25 isheld 'at this time,

. from the platen under the forcing operation of the'adjuster without a-dis'tortion of the metalpf which said bar is composed. The result will be that-the relationship between the bearing eye 26 of thebar and the part by which it is surroundedwill be permanently changed, such change bein indicated in the present instance in lFig. 4,

which shows the lower case type at the rintlng point after the bar of Fi 2 has been properly lengthened and the adjusting tool withdrawn to permit free swinging of the lengthened bar. It will be observed that as a result of the adjusting operation the body of the bar has, as a whole, moved with respect to the bearing eye 26', this movement a being upward or toward the printing point and, as illustrated, being the result of a hange or distortion of the neck portion 27.

In 4 the change iss omewhat exaggerated so thatxit may be more-clearly understood. In the case of a bar which is -a trifle too long the locking tool is applied as in Fig. 2 and the type end of the bar is then forcedslightly toward the'platen so as to shorten the distance between the'type and the pivotal axis of the bar. This forcing will result in a distortion of the bar such as is illustrated on an exaggerated scale in Fig. 5. -Of course, as a result of the adjusting operations, the change in'the shape of the bar may not in all cases be'as regular as that illustrated in Figs. 4 and 5 and may occur at different places; but it will be obvious that by reason of the novel construction of the pivotal or enlarged end portion of the bars, the effective length of the bars may be varied, that is, a permanent alteration is facilitated whereby the bars may be individually lengthened or shortened. without removing them from their common pivot 7 and without disturbing any of the bars except the one which is under adjustment. It will further be understood that my invention provides for correcting imperfections in alinement due to variations in the length of the type bars. Of course, imperfections of alinement due to other causes are to be changed in other ways than by altering the lengths of the bars.

Various changes may be made without departing from the spirit and scope of my invention What I claim as new and desire to secure by Letters Patent, is
